of the beam 2 and at its rear end with the succeeding frame 6 in the vicinity of the land side edge thereof. Draft rods 11 are connectedwith the beam 2 one at the projecting end portion thereof and the other at 'a' point between the land and furrow edges of the frame 1 and the said rods 11 converge toward each other at their forward ends and are pivotally secured to a draft plate 12 at different points. A clevis 13 is pivotally connected-with the draft plate 12 and serves as means for connecting the series of gang frames with the frame of a tractionengine or other draft means. A vertically disposed shaft 14 is journaled at the furrow edge of the frame 1 and a furrow wheel 15 is journaled upon the lower end portion of the said shaft and-ispitched at an angle to a vertical plane as is usual in such'wheels. A vertically disposed shaft 16 is journaled at the land side edge of the frame 1 and a land side wheel 17 is journaled at the lower end of the said shaft 16. An arm 18 is fixed to the upper end. of the shaft 16 and an arm 19 is fixed to the upper end .of the shaft 14. A longitudinally extensible rod 20 connects the arms 18 and 19 together so that they are caused to swing in unison about the respective shafts to which they are attached. Arms 21 and 22 are rigid with the arm 19 and in practice the three said arms are made in one integral piece. A' rod 23 is connected at its rear end to the forward end portion of the arm 21 and at its forward end is connected with the draft plate 12 at a point between the forward and rear ends of the said plate. A vertically disposed shaft 24 is. 'journaled at the furrow ed e of the frame 6 and a flirrow wheel 25 1s journaled' at the lower end of the shaft 24. The said wheel 25 is also pitched at an angle to a vertical plane. A vertically disposed shaft 26 is journaled at the land side edge of the frame 6 and a land side wheel 27 is journaled at the lower end of the said shaft 26. An arm 28 is fixed to the upper end of the shaft 26 and an arm 29 is fixed to the upper end of the shaft 24. A longitudinally extensible rod '30 pivotally connects the arms 28 and 29 together whereby the said arms are constrained to rotate in unison. about the axes of their res ective shafts. An arm 31 is rigid with t e arm 29 and in practice is madeintegral with the same. A rod '32 is pivotally connected at its forward end with the arm 22 and at its rear end with the arm 21. The rear portion of the succeeding frame 6 is supported upon a rear furrow wheel 33 in. any appropriate manner. Thus it will be seen that the rear portion of the preceding frame 1 is supported upon the forward portion of the succeeding frame 6 and the said frames have such flexible connection as to enable their respective soil engaging members to properly operate in the soil. Furthermore it will be seen that when draft strain is applied to the plate 12 through the clevis 13, the said strain is transmitted through the rods 11 to the cross beam 2 of the preceding frame 1, at the land side edge portion thereof, also the said draft strain is transmitted through the frame 1 to the furrow side edge portion of the frame 6 and through the rod 10 to the land side edge portion of the frame 6. Thus the draft strain is applied to the frame 6 at theopposite sides of the pivotal connection between the, said frame 6 and the frame 1. Again it will be seen that as the plate 12 is swung to one side or the other horizontally the rod 23 will be moved longitudinally and through the arm 21 the shaft 14 will be turned upon its axis and through the connecting parts the shaft 16 will be similarly turned. This will cause the furrow wheel and the land side wheel 17 to maintain constant relation to the draft plate 12. At the same time the arm 22 swings about'the axis of the shaft'14 and the rod 32 is moved longitudinally which in turn swings the arm 31 about the axis of the shaft 24 and the wheel 25 together with the wheel 27 are turned about the axes of their respective shafts and are also heldin predetermined relative relation to the plate 12 and the furrow and land side wheels of the preceding frame. Thus means are provided. for steering the forward wheels and land side wheels of the members of the set of gang frames in unison with the draft plate 12.

An operators platform 34 is mounted at the forward edge of the preceding frame 1 and a shaft 3.5 is journaled upon the said frame. Rods 36 are pivotally connected with the forward ends of plow beams 37. Lever mechanisms 38 are provided for moving the rods'36 longitudinally and the said upon the platform 34. A lever 39 is fulcrumed upon theforward portion of the frame 1 and is within reach'of one standing upon the platform 34. A shaft 40 is journaled upon the forward portion of the suc-,

ceeding frame 6 and rods 41 are pivotally connected with the forward ends of plow beams 42 andat their forward ends are pivoted to levers 41 mounted upon the shaft 40. The shaft 40 is provided at its inner end with a crank arm 43 upon which is swiveled a bracket 44 The rear end of a rod 45 is pivoted to the bracket 44 and the levers 38 are within reach of one standing said rod at its forward end is pivoted to the lever 39 fulcrumed upon the frame 1 2' When the gang frames are drawn over the surface of the ground and the plows are in contact with thefsoil the swiveled bracket 44 is locatedapproximately vertically above the bearing 7 about midway between the ends of the opening therein that receives Leeaevo the'stud 4 and by reason of the factthat the said bracket 44 is a pivotal connection that attaches the rod 45 to'the crank 43 of the shaft 40- and is in close proximity to the bearing 7 as indicated therelative swinging movement of the frames 1 and 6 will occur approximately coincident with. the bracket 44 as a pivot and therefore such movement will'not have a tendency to rock the shaft 40% the location of the swiveled bracket 44 at another relative position may do. That is to say the lever 39 is held in a fixed position and the rod 45 is inflexible and therefore the pivotal connection be,- tween the rod 45 and the arm 43 of the shaft 40 should be as near as possible the pivotal connection between the stud 4 and the bearing 7 in order that the swinging or rocking movement of the frames 1 and 6 will not affect or tend to turn the shaft 40 in its bearings upon the frame 6. By this ar rangement a flexible connection is established between the lever 39 and the shaft 40 and at the same time there is sufficient-rigidity from the lever 39 when held in a fixed position through the rod 45 to properly hold the shaft 40 against turning in its bearin s. 7

It will e seen that an operator upon the platform 34 may swing any of the lever mechanisms 38 and raise or lower the beams 37 of the plows carried by the frame 1 or the operator standing upon the same platform may swing the lever39 and turn the lever 40 whereby the beams 42 of the plows carried by the frame 6 are raised and lowered. Brace rods 46 are provided at their ends with bearings 47 and one of the said rods has its bearings receiving the upper ends of the shafts 14 and 16 and another of the said rods has its bearings receiving the upper ends of the shafts 24 and 26. These rods serve as means for holding the upper end of the said shafts in proper relation to each other and also serve as means for preventing the said shafts from tending to bind or wear in their bearings.

Where a plurality of plow gangs are used as shown in Fig. 11, the manipulation of the lever 39 of the preceding or forward gang will actuate simultaneously all of the respective plow beams upon the respective following gangs, the connection between all of the respective preceding or intermediate gangs and the last gang being similar to the one shown in Fig. '1, containing two gangs only. Thus the manipulation of the lever 39 of the forward gang as shown in Fig.11 will operate the beams 37 of the plows in the second gang, while the lever 39 of the second gang through the rod 45 will actuate as before described the beams 42 of the last gang.

The detail construction and operation of the plow actuating levers and shafts 39 and 41" respectively,being the subject matter of a co-pending application filed- March 27 1911, Serial No. 6 17,1 06, Patent l lo. 1,014,379, January 9,, 1912,)it is notthought necessar todescribe in detail the construction an application of the rods36 and '41 to the respective plow beams of the-frame, the rods as, shown in Fig.1 being'bro-ken a short distance to the rear of their respective shafts and not shown connected to the plow beams.
